WALL CONSTRUCTION AND CHANNEL BRICK 0R BLOCK THEREFOR.

Specification of Letters Patent. Patented July 22, 1919., Substitute for application Serial No. 695,379, filed May 6, 1912, which was renewed on February 23, 1915,

Serial No. 10,129. This application filed July 16, 1915. Serial No.40,250.

To all whom it may concern:

Be it known that I, ARTHUR HARDON- COURT, J r., a subject of the Emperor of Austria, and a resident of- Brooklyn, New York, in the county of Kings and State of New York, have invented an Improvement in Wall Construction and Channel Bricks or Blocks Therefor, of which the following description, in connection with the accompany ing drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to hollow wall construction and a channel brick therefor, the present application constituting a substitute for my application filed May 6,, 1912, Serial N 0. 695,379, which was renewed on February 23, 1915, as Serial No. 10,129.

The object of the present invention is to provide an improved channel brick and a hollow wall construction embodying such channel brick, which wall construction shall be practically moistureproof and effectively prevent the penetration of moisture from the outer to the inner face thereof, and one in which the longitudinally extending mortarjoints are separated by longitudinally extending air spaces.

A further object of the invention is to produce a moistureproof wall embodying my improved channel brick combined with a facing of standard brick, and to produce a channel brick which in construction and size, shall be adapted for use with standard brick so that a standard brick bond may be projected into and received by the channel brick portion of the wall at any given line of channel brick construction, .thus providing for the efi'ective bonding of the standard brick facing to the channel brick portion of the wall, and whereby ordinary brick may be effectively used at any point in the channel brick portion of the wall for the purpose of closing the open-ended channels and finishing the wall at angles and corners and around window and door openings.

Further objects of the invention will be set forth in connection with the following description of my improved channel brick and hollow wall construction.

The invention is illustrated in the accompanying drawing in which Figure 1 illustrates a transverse section through a hollow wall construction embodying my invention, in which the wall comprises a section constructed of channel brick with a facing of standard brick laid against and bonded thereto.

Fig. 2 illustrates a perspective view of the improved channel brick, such as is illustrated in Fig. 1.

Fig. 3 illustrates a transverse section through a hollow wall construction omitting the facing of standard brick and embodying a slightly modified form of channel brick.

Fig. 4 illustrates a perspective View of the channel brick employed in the wall construction shown in Fig. 3.

, Similar reference characters will be employed throughout the specification and drawing to designate corresponding parts.

In the drawing, 1 represents a suitable foundation upon which the hollow wall construction 2 is built up.

As shown in Fig. 1, the hollow wall construction 2 comprises superimposed longitudinallyextending rows of my improved channel brick 3. The channel brick 3 as shown in Fig. 2, is constructed of clay which is dried and kiln-burned in the usual manner of manufacturing brick, and it comprises a body portion 4, from one surface of which pro ect webs 5, and when the channel brick is made double as shown in Fig. 2, the body portion 4 will correspond in size and dimensions to two standard brick laid parallel and side by side; that is to say, assuming that a standard brick is 4X8, which is the usual size of well known standard brick, the size of the body portion 4 of my channel brick will be 8X8.

When made double standard brick size, my

channel brick asshown in Fig. 2, will beprovided [with a web 5 extending along each of the outer edges of the body portion 4 and' a web 5 located at an intermediate point.

Upon the upper surface of the body ortion 4 the channel brick 3 will be provided with upwardly projecting ribs 6 which extenid parallel to each other and are of a width considerabl less than the space between the depending webs 5 and are positioned directly over the space between the webs 5, thus producing along the outer edges of the ribs 6 the angular recesses or seats 7 with the intermediate recess or seat 8,

extending mortar joints, mortar joints are separate and independent,

Between the webs 5 there are provided open spaces 9 extending parallel to each other from end to end of the channel brick and preferably extending in the form of a groove 10 beneath the ribs 6 longitudinally thereof, whereby the wall of the channel brick is substantially of uniform thickness throughout, and thus a tendency to warp, in manufacture, is counteracted to a great extent.

As heretofore indicated, the double form of channel brick is practically twice the size of two standard brick, and the outer faces 11 are substantially the size and shape of the face of a standard brick; that is to say, assuming that the standard brick is 8 inches by 4 inches in the largest area, and 8 inches by 2 inches in its smaller area or its face area, the sides 11 will be 8 inches by 2 lnches. The wall 2, as before stated, is built up of a. plurality of superimposed rows of the channel brick 3 laid so that the spaces 9 between the webs 5 will run longitudinally of the wall and in the construction of the wall the webs 5 will be seated in the independent mortar joints 12 formed by the mortar 1n the recesses 7 and 8, the ribs 6 of one channel brick being received within the spaces 9 of a superimposed channel brick.

By this construction, it will be noted that the hollow wall construction". comprises longitudinally extending channel brick inclosing longitudinally extending air spaces and separate and independent longitudinally and that as the no moisture can penetrate from one surface to the other surface of the wall. It will be further noted that the air spaces also act as a preventive of the penetration of moisture through the wall.

The upwardly extending ribs are made somewhat narrower than the space between the webs, so that while they form a guide for accurately positioning one channel brick on another, the ribs nevertheless, are substantial in size and have not the tendency to warp during the baking process or to become distorted, thus insuring at all times the ready insertion of the ribs in the space or opening between the webs.

The wall as shown in Fig. 1, comprises a facing of standard brick 13, which are laid up in the usual manner and held in position by means of mortar joints 14, and as the standard brick and the channel brick are of the same height and length, when the standard brick are laid as shown in Fig. 1, each layer thereof will be in the same plane as any particular row of channel brick, so that when it is desired to secure the facing of standard brick and the hollow wall together, as by means of a bonding row 15 of standard brick, this may be accomplished by dividing the channel brick in this row or by using a channel brick having a single channel and inserting the standard brick so that a portion of the standard brick extends into the hollow -wall construction and a portion of it extends into the facing of standard brick, as shown at 15. In making this bonded connection,--one of the upstanding ribs 6 of the channel brick in the course below will be partially broken off or removed as shown at' 16.

, It will be noted that I have produced a channel brick which lends itself readily because of. its size with relation to a standard brick, to being combined with such standard brick in the building up of a wall.

by means of the projections 17, although I such feature is not essential and may be dispensed with.

Such a wall as I have shown and described in Fig. 1, may receive upon its inner surface plaster or other finish .directly applied thereto, without the necessity of using any other means for receiving and supporting the plaster, and in order to effectively anchor the plaster surface to the wall, the channel brick 3 may be provided along the outer exposed faces thereof with the dovetail grooves 18 which receive a portion of the plaster finish and will effectively hold such finish to the wall surface.

In Fig. 3 the hollow wall is built up of channel brick exactly like the channel brick ing, and in this form of wall the channel bricksuch as shown in Fig. 4 is employed, in which the sides 11 are formed without the longitudinally extending dovetail groove and one side of which is provided with any suitable finish, such as the roughened finish as shown at 1'1, commonly called wirecut finish, corresponding in all respects to the finish of a wirecut standard brick, whereby, when built up into a wall construction, the outer face of the wall will have the appearance of being constructed of standard brick with 'a wirecut finish.

My improved channel bI'lOk is, as before stated, made of any brickmaking material, and while combining all the advantages of lightness and strength of a standard brick, has the additional advantage of being twice the size of a standard brick, while relatively light in Weight, thus permitting the laying of what is the equivalent of two standard brick at a single operation. A further advantage ls the adaptability of the channel brick to be combined with standard brick because of its size with relation to the size of a standard brick. A further advantage 7 is, that while it has all the appearance of a standard brick -when built up into the wall,

of thebrick. A ,further advantage resides in the facility with which the channel brick may be positioned, one row with relation to a sub'jacent row, the positioning of the webs being guided by the ribs and mortar seats as hereinbefore set forth.

I I would point out that in so far as I am aware of the prior state of the art, I am the first to produce a channel brick provided with'a"long itudinally extending air space between parallel webs, the outer faces of the webs or the side faces of the channel brick corresponding insize to the face of standard brick, whereby my channel brick is adapted to be combined, and to readily adapt itself for use with standard brick, and this feature I regard as one of the most important features of my invention.

Of course, it is to be understood that instead of making my channel brick double, as shown in Figs. 2 and 4, it can be made smgle, that is to say, exactly one-half the width, or exactly the size of one of the larger surfaces of the standard brick, in which event the channel brick-would have only two depending webs 5 and only one upstanding rib 6. Otherwise, the construction will be the same as that illustrated and described. Such a brick is shown in the second course from the top of Fig. 1.

My improved channel brick is to be clearly dlstinguished from cement blocks such as shown in the patent to Shaw, #676,803, of June 18, 1901, as unlike such blocks my channel brick are made of'clay and by the use of any usual brick making machines and after beln formed are baked in the usual manner 0 making brick, and in order to prevent the warping of the brick while being baked all parts thereof are preferably of uniform thickness. Most important, however, is that my channel brick are of such a size as to be readily combined with standard brick in the formation of a wall.

Having described my invention, I claim: 1. Hollow wall construction, comprising horizontal rows of superimposed longitudinally extending channel brick, each channel brick comprising a body portion and parallel webs projecting from the body ortion at right angles thereto and space apart fromfeach other forming an open channel, the space between the projecting webs being open from end to end and the webs and body portion being co-extensive in length, and the outer faces of such webs bein rectangular and approximately corresponding in size to the face of a standard'brick, the whole being of substantially uniform thickness throughout; the channel brick in one row combining with the body portions of the channel brlck of a subjacent row to form longitudinally. extending superimposed air spaces; and longitudinally extending parallel mortar joints uniting said rows'of channel brick, the mortar joints being adjacent the opposite faces of the wall and separated by the air space.
